Microfabricated heavy metal ion sensor
Sensors and Actuators B: Chemical, 1995 Abstract A novel microfabricated electrochemical sensor has been developed for the detection and measurement of heavy metal ions in aqueous media. The sensor consists of a silicon substrate, on which is fabricated an electrically interconnected, but diffusionally isolated, array of thin-film iridium microelectrodes upon which a thin film of mercury ...

Wastewater Treatment from Heavy Metal Ions
IOP Conference Series: Earth and Environmental Science, 2021 Abstract The article is devoted to the sorption treatment of industrial effluents, which contain heavy metal ions (HMI) by the natural clay mineral kaolinite - an activated adsorbent. The main sources of HMI receipts are revealed - industrial and agricultural production. The influence of heavy metals on human health is considered.
